6.BATTERY SAVER (SLEEP M ODE)
The meter w ill automatically enter the
“sleep mode” if there is no
function change or button press for 10minutes, but it w orks as soon
as you turn the rotary function sw itch or push dow n any button
.
7.POWER TOOLS AND AM ALL APPLIANCES
This test w ould also apply to other similar equipment that has a line
cord. For double insulated pow er tools, the megohmmeter lead
show n connected to the housing w ould be connected to some metal
part lf the tool(e..g chuck,blade).
Note:
The sw itch of the device must be in the “ON” position and the
main pow er should be disconnected.
MOTORS
AC-Disconnect the motor from the line by disconnecting the w ires at
the motor terminals or by opening the main sw itch. If the main sw itch
is used and the motor also has a starter then the starter must be
held, by some means, in the “ON” position. In the latter case, the
measured resistance w ill include the resistance of the motor, w ire
and all other components betw een the motor and the main sw itch. If
a w eakness is in dicated, the motor and other components should
be checked individually. If the motor is disconnected at the motor
terminals, connect one megohmmeter lead to the grounded motor
housing and the other lead to One of the motor leads.
DC- Disconnect the motor from the line. To test the brush rigging,
field coils and armature connect one megohmmeter lead to the
grounded motor housing and the other lead to the brush on the
commutator. If the resistance measurement indicates a w eakness,
raise the brushes off the commutator and separately test the
